NON-REFILLABLE RECEPTACLE.

SPECIFICATION formingpart of Letters Patent No. 721,494, dated February24, 1903. Application filed March 6, 1901. Serial No. 50,007. (Nomodel.)

To all whom, it may concern.-

Be it known that I, HENRY W. AVERY, a citizen of the UnitedStates,-residing at Cleveland, in the county of'Ouyahoga and State ofOhio, have invented a certain new and useful Improvement inNon-Refillable Receptacles, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings.

This invention relates to improvements in so-called non-refillablebottles -that is to say, bottles or analogous receptacles which afterhaving once been emptied cannot be re-- filled. Such devices asheretofore constructed have frequently inclosed suitable valves oranalogous devices which permit the contents to be emptied from saidreceptacle, but will not permit other liquid to be put into it. Variousforms of baffles have also been employed to hold these valves inoperative position.

The present invention has for its object to provide a baffle and meanswhich prevent its removal after once inserted into the bottle.

The invention consists of a baffle-plug having an externalcircumferential groove combined with a compressible spring-ring whichwhen in its normal condition lies partly within and partly outside ofsaid groove, but which is capable of being compressed, so as to liewholly within said groove; and it also consists in the combination ofsaid baffle-plug and ring with a receptacle in whose neck is an annularenlargement into which said Ieraining-ring is adapted to project whenthe ring is in its normal condition.

In the drawings, Figure l is central vertical section through the neckof a bottle, showing the baffle-plug therein, but before it reaches thepart wherein it will be held. Fig. 2 is a similar View showing thebaffle-plug in place. Fig. 3 is a horizontal sectional view on line 3 3of Fig. 1, and Fig. 4 is a horizontal sectional view on line 4 4 ofFig.2. Fig. 5 is a side elevation of a modified form of halideplug.

Referring to the parts by letters, A represents any receptacle, hereshown in the form of a bottle. The neck a of this bottle has in itslower end a seat a. for the valve. Its upper end forms a cork-receivingportion a and between these two parts there is an annular enlargement orrecess (1 into which the bafflering may project. The valve-seat a,asshown, is a conical recess which'contains a light ball B and above it a"heavy ball B. The upper end of this conical recess is of smaller areathan the cork-opening a Therefore the baffle-plug 0 may be insertedthrough the cork-opening, but may not pass into said conical hole, butwill seat itself over the same. 7

The baffle-plug 0 maybe made of porcelain, glass, or any desiredmaterial. Its exterior is slightly smallerthanthe interior of thecork-opening a wherefore it may be easily passed through this part ofthe neck. This plug is provided near its lower end with an externalcircumferential groove 0. It is also provided with openings 0, leadingfrom its top down to said groove, which openings are preferably crooked.These openings may pass through the plug or may be in the form ofgrooves in its sides. I

D represents the retaining-ring. It is preferably a split ring withoverlapping ends and made of spring-wire bent into approximately starshape. When in its normal condition, the points dof said ring extendbeyond the periphery of the plug, while the inner parts d thereof lie insaid groove 0. It is possible, however, to contract or compress thisring so that its external diameter shall be no greater than the externaldiameter of the plug, wherefore said ring'may lie wholly in the groovein the plug. This condition of the ringis shown in Fig. 4.. Thisspecific construction of the ring is not essential to the genericinvention and any other form of spring-ring which normally is of suchshape and size that it willlie partly within and partly outside of saidgroove, but which may be compressed so as to lie wholly in the groove,may be substituted for the ring shown.

In assembling the parts the valve-balls'are first inserted. Then thering D is placed in the groove 0 in the baffle-plug and compressed, asshown in Fig. 3, and then the plug carrying the ring, as shown, isinserted into the neck of the bottle and pressed downward. When saidgroove 0 comes into the plane of the enlargement or recess 0. 111 theneck of the bottle, said ring expands to its normal condition andthereafter prevents the removal of the bafiie-plug, although it permitsa slight longitudinal movement of the plug, which is limited by theengagement of the ring with the upper end of the recess in the neck andby the engagement of said ring with the lower edge of said recess or bythe engagement of the lower end of the plug with the part of the neckimmediately below it.

In Fig. 5 a plug 0 is shown in which the lower end of the plug is madein the form approximately of a hemisphere and is adapted to fit theupper end of the hole a of the neck of the bottle and to serve as avalve, which will prevent any fluid from being introduced through theneck into the bottle when the bottle is upright. This last constructionWhile cheaper than the ball-valves shown in Figs. 1 and 2 is notbelieved to be as efficient.

Having described my invention, 1 claim 1. In a non-refillablereceptacle, a neck having an enlarged portion and an internal annularrecess and a contracted valve portion leaving an annular seat betweenits upper end and the annular recess, combined with a plug adapted torest on said seat and having an external groove opposite said internalannular recess in this position of the plug, an offset groove on theoutside of the plug leading from the upper end to its annular groove, aspring located in the annular groove of the plug and adapted to engagein-the annular recess in the neck of the bottle, and a suitable valveoccupying the contracted valve portion of the neck, substantially asdescribed.

2. In a non-refillable bottle, the combination with a neck having aninternal annular recess, and another internal annular recess adjacentthereto, a plug for the mouth of said bottle having an annular groove,and a zigzag groove on the outside thereof, a spring in said annulargroove adapted to operate in said recess, a tapering valve-seat, and asuitable valve, substantially as described.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
